Importance of the construction balance on the LEGO Mindstorms robot movement

The balance of the construction of the robot has a great influence on how it will move. This is especially true if you would like to move in a straight line. If the robot is slightly heavier on the right it will move to the right. Here we have two robots - a Five Minute robot and a Box Robot and we will discuss the differences in the constructions and why the box robot is much better than the Five Minute even though it is using the same parts. 

Front or Rear wheel drive for more precise LEGO Mindstorms robot movement?

Should the robot be with a Front Wheel Drive or a Rear Wheel Drive to make it more precise? The answer is - front wheel will probably give you better results, but the wheel drive is not the most important thing. In this video tutorial on the LEGO Mindstorms Robots, we will do a few experiments to discuss the influence of the wheel drive on the precision of the movement.  

Box Robot Two. With fewer parts and only one motor.

Here we start with a second box robot that we would like to build. It is in a way improvement to the first robot and we would take a look at its features.
